Hi Pranith, Ok, I understand what you are saying. I originally had followed the online documentation: "For example, to create a pure replicated volume with two storage servers: # gluster volume create test-volume replica 2 transport tcp server1:/exp1 server2:/exp2 Creation of volume replicate has been successful" now this creates a purely replicated volume with two replica's But this does not allow you to add more replicas on the fly at a later date. Is there another way to setup the volume so that it can be expanded in a purely replicated manner with out distribute? I have set up a three node replicate that I can remove bricks from and add them back in, but then I'm limited to three nodes and can not add additional as required. This seems to suggest that elastic volume management is only in a distribute type and not replicate. I do understand that replicate will not expand my storage size, just expand my data safety with more copies :) Is this making sense? Pat. On 06/02/2011 9:49 PM, Pranith Kumar.
